First Claim
Patent Images
1. A method of treating an ailment of a patient using a neuromodulation device, comprising:
- delivering electrical energy at a first frequency to a first set of electrodes having a first combined electrode impedance;
receiving a signal to switch from delivering electrical energy at the first frequency to delivering electrical energy at a second frequency greater than the first frequency;
responsive to receiving the signal to switch, automatically instructing the neuromodulation device to deliver the electrical energy at the second frequency to a second set of electrodes having a second combined electrode impedance less than the first combined electrode impedance instead of at the first frequency to the first set of electrodes; and
delivering the electrical energy at a second frequency greater than the first frequency to the second set of electrodes having a second combined electrode impedance less than the first combined electrode impedance.

Abstract
An electrical neuromodulation system and method of treating an ailment of a patient using a neuromodulation device. Electrical modulation energy is delivered at a first frequency from the neuromodulation device to a first set of electrodes having a first combined electrode impedance. A second set of electrodes having a second combined electrode impedance less than the first combined electrode impedance is automatically selected. The electrical modulation energy is delivered at a second frequency to the second set of electrodes, wherein the second frequency is greater than the first frequency.
